Ampatop RF black (plus)
Low-flammable wall membrane for façades with open joints
Two-layer, low-flammable black wind seal for façades with open joints.
- The fleece is made using recycled PET bottles (100 %): Protects the environment
- UV stable
- Ten-year product warranty for joint width up to 50 mm / 40 %
- Fire behaviour: B-s1, d0
Two-layer, low-flammable black wind seal for façades with open joints, consisting of a PET fleece with TPU coating. According to EN 13859-2 for walls with open joints, artificial ageing was carried out with 5000 hours of UV exposure (standard is 336 hours).

Ampatop RF black (plus) can be laid horizontally or vertically with the coated black side facing outwards. The laying direction must not be different on each side of the building.
Roll out the membrane, line it up, cut it to length, pull it tight and fix it in place, e.g. using stainless steel tacks (this should be invisible inside the overlap, which must be at least 10 cm). Always mount the final mechanical fixation after laying (e.g. counter battens)! Ampacoll ND Pads (nail seals) or Ampacoll ND.Band (nail sealing tape) should be used for this.
The integrated tape, Ampacoll Profix liquid adhesive or Ampacoll UV/ Ampacoll UV flexx acylic tape should be used for the wind and waterproof bonding of the overlap. This best-practice method also applies to necessary penetrations (e.g. for air vents, balcony mounts and cable holes) as well as window joints. Visible leakage of the adhesive must be avoided.
Ampacoll Profix is also used to bond Ampatop RF black (plus) to metal furring within the insulation layer. The maximum distance horizontally or vertically is 1.45 m, and the minimum width of the profiles is 4 cm. The insulation must fill the entire cavity and be laid evenly and secured in place, so that the façade membrane is not negatively affected (no bulging, pushing out, etc.). When installing on wooden materials, pressure-resistant insulating materials or similar, it is recommended to bond using Ampacoll Profix every 70 cm horizontally and vertically, especially when only individual or sporadic brackets are installed for final fixing. The maximum distance between individual attachments is 70 cm (horizontal and vertical). N.B.: Protruding attachments must be split at insulation level and should not penetrate the membrane (e.g. two-piece brackets with clamping flanges).
